  • Inside Alnylam's Playbook For High Volume siRNA Production

    As one of the first companies to establish a chemoenzymatic ligation platform, Alnylam's Maines and Nechev are in the perfect position to espouse wisdom on the practical aspects and remaining challenges of implementing enzymatic ligation at a large scale. Here in this installment, Maines and Nechev outline what they’ve learned thus far about the science of enzymatic ligation, while also paying credence to the unknowns and existing barriers that, as a frontrunner, Alnylam will inevitably (but willingly) be tasked with facing in the future.

  • ARW's ATMP Manufacturing Must-Reads (2024 NEW YEAR'S RESOLUTIONS EDITION!)

    Day-in and day-out, I write, read, listen to, and watch as much content as I can about CGT and RNA therapy manufacturing, in particular, and/or other ATMP industry-related topics that you should at least be aware of in the manufacturing facility. Once a month, I compile the articles and industry updates I think are most worthy of your time into an unconventional newsletter format (below) and send them out via email.

  • Moderna & The Global mRNA Supply Chain: Regulatory Lessons Learned

    One of the most important reminders I took away from Moderna’s experiences ushering its mRNA vaccine onto the global market is that a commercial manufacturing process must also be accompanied by a commercially ready supply chain. Though sufficient physical volumes of each raw material and a redundant supplier network are necessities, physical scale is not the only “CQA” for which we must account when commercializing our supply chain. 

  • Can America's Retreat On mRNA Be Europe's Opportunity?

    With HHS winding down mRNA vaccine development under BARDA, could Europe seize the opportunity to lead in mRNA innovation? Exploring the policy shift's implications.

  • A "Hot Take" on Personalized mRNA Medicines

    mRNA’s small-scale and cell-free production are often-touted benefits in the personalized medicines sphere. But as I reviewed my notes from the BioPhorum ATMP member event, I found myself coming face to face with a difficult truth.

  • Beyond The Gold Standard(s): Modernizing Oligonucleotide Synthesis

    A few weeks ago, I had the chance to sit down with OPT Congress speaker Phil Baran, Richard Lerner Chair Professor, Department of Chemistry, Scripps Research. Baran was slated to (and did) present a keynote on the innovations shaping the next generation of oligo synthesis. Here, I share the biggest takeaways I had from our conversation, touching on how he sees the science of oligo chemistry and manufacturing advancing in the near and far future.

Is synthetic DNA set to replace traditional E. coli-based plasmid DNA in mRNA manufacturing? Panelists weigh in on recent poll results, examining where cell-free DNA synthesis fits today—from rapid-response, small-batch personalized therapies to large-scale production. 

In this Advancing RNA Live segment, several speakers raise concerns about the industry's ability to accurately measure impurities, particularly dsRNA, arguing that current analytics are insufficient, especially for high-dose therapeutics.

This Advancing RNA Live clip dives into the biggest challenges in mRNA purification and the critical debate on where to focus investment. Here, our three mRNA PD experts argue for a holistic process development strategy, challenging the traditional wisdom of optimizing the upstream process at any cost.

Can we actually achieve metric-ton siRNA production using enzymatic ligation? While the ligation step is highly scalable, upstream "blockmer" synthesis remains the primary bottleneck. Advancing RNA Live panelists Claire MacCleod and Jill Caswell discuss the shift from "scaling out" to "scaling up" and lessons learned in the process of achieving larger-scale production.
